The Dark Tide by Andrew Gross

What the cover says:
"They say bad luck comes in threes. But for Karen Friedman's family, bad luck is just the beginning.
It starts with her husband Charlie's investments going wrong and the sudden death of a much-loved family pet. Then one morning Charlie takes the train to work - straight into a lethal terrorist blast. For Karen and her children, all that remains of Charlie is a memory.
Or is it? When the Friedmans being to receive terrifying threats Karen turns to Detective Ty Hauck for help. Hauck's family fell apart too after a tragic accident he still blames himself for. Now he's determined to keep Karen's family safe. But Hauck doesn't know how the people who investigate Charlie have a way of ending up dead..."

This is an ok book, keeps moving along, keeps you guessing, but didn't grab me somehow. Similar to the ones that Andrew Gross has co-written with James Patterson - good but not great.
